<P class=MsoNormal>Hi,<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>I am trying to figure out how to capture image frames most
efficiently. Each frame is approximately 20Mbytes.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>I am trying to achieve frame rate of 1-2 frames per second.
The packets are being received over a Gig eth dedicated link. ( Packets
are sent over that link using only one source).<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>I am unable to achieve this frame rate using winpcap. Would
it be helpful to modify the Winpcap source code for better performance ? Has
anyone here have any experience in modifying the winpcap source to achieve
higher frame rate capture ?<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>Thanks for your help in advance<o:p></o:p></P>
<P class=MsoNormal>Regards<o:p></o:p></P>
